Can you still remember some of the natural wonders we talked about? Let's do a quick review. What natural wonder is covered with white frost? S1: The tree we saw in the picture. T: Right! And what is the bright light in the sky that some of you mentioned? S2: The northern lights. T: Excellent. Now, think about this. Why do you think nature is so amazing? Discuss in pairs for a minute and then share your ideas. S3: Nature is amazing because it has so many different and beautiful landscapes. S4: There are also so many unique animals and plants in nature. 阅读前准备 背景知识引入 T: Today, we are going to read an article that further explores the wonders of nature. Before we start reading, let's think about how nature and human life are connected. For example, we get food from nature. What else do we get from nature that is important for our lives? S5: We get fresh air from the plants in nature. S6: We use wood from trees to build houses. 预测文章内容 T: Now, look at the title of the passage “[Title of the passage in the textbook]”. What do you think the passage might be about? Make a guess. S7: Maybe it will talk about some special natural places. S8: It could be about how nature helps us in different ways. 文章阅读 快速浏览文章，掌握主旨大意 T: Now, I want you to skim the passage quickly. Skimming means reading quickly to get the main idea. Try to finish it in 2 minutes. After that, tell me what the main idea of the passage is. Start! (Students skim the passage) T: Time's up. Who can tell me the main idea? S9: The passage is about how amazing nature is and how it influences our lives. T: Very good. You got the main point. The passage indeed focuses on the amazing aspects of nature and its impact on us. 仔细阅读文章，完成细节理解任务 T: Next, let's read the passage carefully. This time, I have some detailed questions for you. Read paragraph by paragraph and answer the questions on the screen. For example, in paragraph 1, what is the first amazing thing about nature mentioned? Start reading and answering the questions. (Students read carefully and answer questions) T: Let's check the answers. For the question about paragraph 1, who can answer? S10: The first amazing thing is that nature provides us with beautiful views. T: Great. Now, for paragraph 2, what examples does the writer give to show nature's power? S11: The writer mentions strong winds and big waves as examples of nature's power. 分析文章结构 T: Now, let's analyze the structure of the passage. How many parts can we divide this passage into? And what is the main idea of each part? Discuss in groups of four. (Students discuss) T: Which group wants to share your ideas? Group 1 representative: We think the passage can be divided into three parts. The first part is the introduction, which tells us nature is full of wonders. The second part lists different amazing aspects of nature, like its beauty, power, and how it gives us resources. The third part is the conclusion, saying we should respect and protect nature. T: Well done. Your group has a very clear understanding of the passage structure. 语言知识讲解 重点词汇讲解 T: In the passage, we come across some new and important words. Let's look at the word “amazing”. We all know it means very surprising and causing a feeling of great admiration. Can you think of some synonyms for “amazing”? S12: Wonderful. S13: Fantastic. T: Right. Now, make a sentence using “amazing”. S14: The view from the top of the mountain is amazing. T: Good. Another word is “provide”. It means to give someone something that they need. The common structure is “provide sb. with sth.” or “provide sth. for sb.” For example, The sun provides us with light and heat. Can you make a sentence using “provide” with the structures I just mentioned? S15: The school provides us with new books. 关键句型讲解 T: Look at this sentence in the passage: “Not only is nature beautiful, but it is also very powerful.” This is a special sentence structure. “Not only... but also...” is used to connect two similar ideas, and when “not only” is at the beginning of the sentence, we need to use an inverted word order. Let's make a similar sentence. For example, “Not only is he good at math, but he is also excellent at English.” Now it's your turn. S16: Not only is she kind, but she is also very helpful. 文章深层含义探讨 人与自然的关系 T: After reading the passage, we know nature is amazing. But think deeper, what kind of relationship should we have with nature? Discuss in your groups and give some reasons. (Students discuss) T: OK, time to share. Which group wants to start? Group 2 representative: We think we should have a harmonious relationship with nature. Because nature gives us so much, like food, water, and a beautiful living environment. If we don't protect it, we will lose these things. T: Very good. Another group? Group 3 representative: We should respect nature. We should not destroy the habitats of animals and plants. For example, if we cut down too many trees, many animals will lose their homes. 保护自然的行动 T: Since we know we should protect nature, what can we do in our daily lives to protect it? S17: We can save water by turning off the tap when we don't need it. S18: We can use less plastic to reduce pollution. 课堂总结 T: Class, today we read an interesting passage about amazing nature. We learned how to skim and scan the passage to get the main idea and details. We also learned some new words and sentence structures, like “amazing”, “provide”, and “Not only... but also...”. More importantly, we discussed the important relationship between humans and nature and how we can protect nature. Remember these points and try to use them in your future learning and life. 作业布置 T: For homework, first, write a short summary of the passage we read today. Include the main idea, important details, and your own thoughts about nature. Second, find an article about nature in English from a newspaper, magazine, or the Internet. Read it and write down three new words or phrases you learned from it. Next class, we will share our findings. 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
